I put new front and rear Monroe “sensa-trak” shocks on my reg. cab 2wd Tacoma a few days ago. I got them at Advanced Auto They had two options this shock and some other for half the price. I went with the Monroe because the counter guy told me this shock provides a much softer ride. The rear is a gas shock. It turns out the ride is real rough! I’m going to take them back. The truck handles good but I feel every little bump, it’s like riding a go-cart and its killing my back. Can anyone explain why it’s such a rough ride, should I not use a gas shock. I think most the rough ride is coming from the rear which has the gas shock. Here are the two part numbers of the shocks 37111st and 37112st
